E Series Service Manual
Preface
ZOLL® Medical Corporation’s E Series® Service Manual is intended for the service technician whose responsibility is to identify malfunctions and/or
make repairs at the subassembly level. The ZOLL E Series Service Manual has five main sections and one appendix.
Preface—Contains safety warnings and an overview of the manual’s contents. Be sure to review this section thoroughly before attempting to use or service
the E Series unit.
Chapter 1—Maintenance Tests explains how to check the defibrillator’s performance using a series of recommended checkout procedures to be
conducted every six months.
Chapter 2—Troubleshooting provides a listing of the procedures and error messages to help the service technician detect faults and repair them.
Chapter 3—Replacement Parts List displays a complete list of ZOLL part numbers for field replaceable parts available for the E Series unit, allowing
the service person to identify and order replacement parts from ZOLL.
Chapter 4—Functional Description provides technical descriptions for the E Series major subassembly modules.
Appendix A—E Series interconnect diagrams and maintenance checklists.
Safety Considerations
The following section describes general warnings and safety considerations for operators and patients. Service technicians should review the safety
considerations prior to servicing any equipment and read the manual carefully before attempting to disassemble the unit. Only qualified personnel should
service the E Series unit.
Federal (U.S.A.) law restricts this unit for use by or on the order of a physician.
Safety and effectiveness data submitted by ZOLL Medical Corporation to the Food and Drug Administration (FDA) under section 510(K) of the Medical
Device Act to obtain approval to market is based upon the use of ZOLL accessories such as disposable electrodes, patient cables and batteries. The use of
external pacing/defibrillation electrodes and adapter units from sources other than ZOLL is not recommended. ZOLL makes no representations or
warranties regarding the performa nce or ef fectivenes s of its product s when used in conjunction with pacing/d efibrillation elect rodes and adapter units fro m
other sources. If unit failure is attributable to pacing/defibrillation electrodes or adapter units not manufactured by ZOLL, this may void ZOLL's warranty.
Only qualified personnel should disassemble the E Serie s unit.
WARNING! This unit can generate up to 2250 volts with sufficient current to cause lethal shocks.
9650-1450-01 Rev. Av
E Series Service Manual
All persons near the equipment must be warned to STAND CLEAR prior to discharging the defibrillator.
Do not discharge the unit’s internal energy more than three times in one minute or damage to the unit may result.
Do not discharge a battery pack except in a ZOLL SurePower™
Charger Station or compatible ZOLL Battery Charging/Testing unit.
Do not use the E Series in the presence of flammable agents (such as gasoline), oxygen-rich atmospheres, or flammable anesthetic s. Using the un it near the
site of a gasoline spill may cause an explosion.
Do not use the unit near or within puddles of water.
Note:The E Series is protected against interference from radio frequency emissions typical of two-way radios and cellular phones (digital and analog)
used in emergency service/public safety activities. Users of the E Series should assess the unit’s performance in their typical environment of use
for the possibility of radio frequency interference from high-power sources. Radio Frequency Interference (RFI) may be observed as shifts in
monitor baseline, trace compression, or transient spikes on the display.

Maintenance Tests
Overview
The E Series has two checkout procedures: the operator’s shift checklist and the extensive six-month maintenance tests checkout procedures.
Because the E Series units must be maintained ready for immediate use, it is important for users to conduct the Operator’s Shift Checklist procedure at the
beginning of every shift. This proce dure c an be c omplet ed in a few mi nutes an d re quires no additional test equipment. (See the ZOLL E
Guide for the Operator’s Shift Checklist.)
A qualified biomedical technician must perform a more thorough maintenance test checkout every six months to ensure that the functions of the E Series
unit work properly. This chapter describes the step by step procedures for performing the six

ECG Front End
The ECG front end provides an electrically isolated serial interface between the main system board functions and patient interface ECG connectors. It
performs the following:
• Analog ECG amplification and signal cond itioning.
• Pacemaker pulse detection.
• ECG signals acquisition and analog to digital conversion.
• ECG 3/5/12-lead detection.
• ECG leads off detection.
• Front-end defibrillator protection.
• Isolated power conditioning.
• Patient impedance measurement via MFE or paddles.
Multifunction Electrode (MFE)/PADS (System Board and High Voltage Module)
Selected for optimal performance for the application, a dedicated ECG amplifier with a limited bandwidth processes the signal. It is th en chopper
modulated and coupled to the system sid e via an is olation transformer. On the system side, the signal is sy nchronou sly demodulated, converted by a 10 bit
A/D at 250 samples per second and digitally processed by the main control unit of the system board.
To measure thoracic impedance, a high frequency (HF) measuring current passes through the patient’s chest and measures the resulting voltage across the
electrodes. After amplification, the impeda nce si gnal i s synchron ously demo dulated. It is t hen co nverted to a stre am of pul ses with freq uency proportion al
to the measured impedance.
CPU and EPU
The Main System Board contains two microprocessors. A Motorola HC-11 single chip microprocessor is used to acquire, convert and process ECG
signals, (ECU). A Hitachi SH-3 RISC microprocessor acts as the system’s main CPU. The SH-3 CPU has an integrated on-chip multiplier, a cache
memory , a memory management unit as well as data protection and virtual memory functions. It also has a timer, a real time clock, an interrupt controller,
a serial communication interface (SCI), and other peripheral functions necessary for the system oper ation. The memory circuitry includes Flash ROM,
internal flash non-volatile memory and DRAM.
The EPU acquires ECG data and runs the A/D convertor that sends data in the form of a serial stream to the CPU.

High Voltage Module
The High Voltage (HV) module includes the high voltage circuitry required for pacing and defibrillation, including the defib charge circuitry, patient relay,
safety relay, defib capacitor, defib choke and front end protection circuitry for the MFC ECG.
The following table describes the high voltage board components:
Component Function
Solid State Patient RelayControls the delivery of therapeutic energy to patient.
Safety RelayDischarges Defib capacitor into the internal discharge
resistor when defibrillator is not in use.
Defibrillator CapacitorStores energy for therapy.
Defibrillator ChokeConditions waveform delivered to the patient.(DSW)
Front End Protection Circuitry for
the MFC ECG
Protects ECG front end against defibrillator pulses.
Defibrillator Charging and Discharging
The defibrillator charges and discharges high voltage capacitor energy. A user can initiate a charge in three ways by 1) pressing the cha rge button on the
front panel; or (2) pressing the charge button on the paddles; or (3) configuring unit to charge automatically when it detects a shockable rhythm following
an ECG analysis. To initiate a discharge, a user depresses both shock buttons on the paddles or depresses a single shock button on the front panel.
The defibrillator circuit charges the high voltage capacitor to the energy level the user specifies.This circuit also provides feedback to the main system
board on the high voltage capacitor's voltage level and discharges the high voltage capacitor energy through paddles or the universal cable. The
defibrillator portion of the high voltage circuitry is active only when the front panel selector switch is set to DEFIB (or set to ON for AED units).
Charging
The charging process starts when the Main System Board detects a charge request. The defibrillator circuits begin charging the high voltage capacitor to
the target voltage or energy that the user selects on the front panel display. The Main System Board continuously monitors the capacitor voltage signal to
ensure that the high voltage capacitor charges at the proper rate. When the target voltage is reached, the Main System Board initiates a continuous beeper
tone to indicate that defibrillator is ready to discharge. The target energy level displays on the display screen.
The defibrillator holds the energ y for 60 sec onds for manual un its and 15 seconds for AED units, refreshing the energy level as necessary. An intermitten t
beep tone sounds during the last ten seconds (five seconds for AED unit) of the hold period. After the 60 second period, if the defibrillator has not been
9650-1450-01 Rev. A4-7
E Series Service Manual
discharged, the ener gy is dissi pated i nto the in ternal discharge resistor by closing the safety relay (XSAFREL). The un it disc h arges internally and displays
a warning message if it is not functioning properly.
Unlike previous ZOLL designs that isolated the patient from defib circuitry via an electromechanical patient relay, the E Series utilizes a bank of siliconcontrolled rectifiers (SCRs). As the defibrillator capacitor is charged, the voltage is monitored via R1 - R4, which drive differential amplifiers referred to
the system ground. These resistor dividers split the capacitor voltage more or less equally above and below ground in order that the positive capacitor
terminal is approximately 1100 volts above ground, and the neg ative capacitor terminal is approximately 1100 volts below ground (at 200J setting). The
voltage at the patient electrodes is set by the divider RN1 and RN2. These networks are each 5X 25 M (125 M total) whose total resistance is specified to
be 125 M +\- 1%. As a result, the patient is nominally at ground and the hot switch bank is split into a ‘positive’ side and a ‘negative’ side.
Discharging
Initiating a discharge provides voltage to the patient relay and notification to the Main System Board through the PADMON signal. The Main System
Board then controls activation of the patient relay. Energy delivered to the p atient goes through t he biphasic bridge/D AC assembly to create a defibrillat ion
waveform. When the patient discharge SCRs are deactivated, the safety relay closes to internally dissipate any remaining energy.
If the E Series is in the self test mode, the energy is delivered internally. The microprocessor calculates the actual delivered energy from the current
waveform and displays a TEST OK message on the display, if the self test meets the appropriate criteria. If the criteria are not met, a TEST FAILED
message displays.
High Voltage Capacitor Monitor
Before charging the defibrillator, the High Voltage Capacitor monitor runs a self test to check the pace relay. The pace relay controls the high voltage
circuitry configuration either for generating pace pulses or for charging the high voltage defibrillation capacitor.
The defibrillator capacitor is shunted for safety reasons with a resistor and relay to internally dissipate any energy remaining. When the Main System
Board initiates a charge, this relay opens by providing a low level on signal XSAFREL. The safety relay is a biased reed switch. The relay is driven by
Q318.
The pace relay driver is a grounded source switch Q308 that is biased on by R 593. It is hel d of f by Q330 when XPACEREL is '1' false. When XPACEREL
comes true, Q330 is turned off, and Q308 is no longer clamped off.
The high voltage capacitor is charged by converting the system battery voltage to a pulsed high voltage by way of transformer T1. The basic operating
frequency signal that is used to switch transistor Q1 providing current in the primary windings of the transformer T1 originates in the system board’s gate
array.
When the high voltage capacitor is charging, the Main System Board independently monitors the capacitor voltage through signal VMON. If the Main
System Board detects an improper level, it halts operation by setting SAFE high. This disables the SCR discharge circuitry and flyback transformer drive.

E Series Service Manual
The patient relay discharges via the signal PATREL_DRV generated by XPATREL and Q304, Q323, and Q322. PATREL_DRV is disabled when
XPACE_SEL is at a logic low.
When the patient relay activation completes, the Main System Board releases the XPATREL signal. Several hundred milliseconds later, the safety relay
closes to ensure the high voltage capacitor energy is completely dissipated.
The Pacer circuit produces and delivers user-controllable pace pulses to the pacing electrodes. To initiate pacing, the front panel switch is turned to
PACER and the OUTPUT and RATE controls are set. Pacing current amplitude is constant during the pulse and is determined by the positio n of the front
panel PACER OUTPUT dial. Pacing pulse rate is determined by the position of the front pan el PACER RA TE dial. The paci ng pulse d uration is fixed at 40
milliseconds.
Pacer/Defibrillator Control Signals
The Pacer/Defibrillator Control charges the high voltage capacitor to a voltage requested by the main system board in response to user energy selections.
It delivers defibrillator energy to the patient through the patient connector to the paddles and pacer electrodes or multi-function electrodes (PADS). This
control also generates pacing pulses at rates and amplitudes requested by the main system board in response to user selections, controls biphasic waveform
defibrillation, and measures pace current and high voltage capacitor voltage by two independent channels.
The following signals control the operation of the Pacer/Defibrillator subsystem:

The system interconnect PWBA receives signals from the Main System Board and in turn controls operation of the stripchart recorder and PCMCIA
functions.
Stripchart Recorder
The Stripchart Recorder module includes a microprocessor, serial interface to the main system board and circuitry which drive the stripchart recorder’s
motor and printhead in response to the main CPU signals. Based upon signals sent by the main CPU, the recorder’s main processor drives the recorder
stripchart motor, formats data for printing on the chart and drives the printhead. It also detects when the sensor drawer is not properly fitted into the unit,
when the paper supply is out and needs to be refilled and the print head temperature.
PCMCIA Slots
The PCMCIA interface module supports two PCMCIA slots which accept Type I and/or Type II PCMCIA cards. These cards may be read or written to.
Data sent by the main CPU is passed to the installed PCMCIA card via the system interconnect PWBA.
Front Panel and Controls PWBA
The User Interface Module provides several functions th at enable the user to operate the unit. The user interface has a display monitor and three rotary
selector switches. One selector switch is for three modes: pacer, monitor and defibrillation. The two other knobs are for pacer output and pacer rate. The
unit interface also has specific buttons for defibrillation, including the ENERGY SELECT button, the CHARGE button, the ANALYZE button and the
SHOCK button. The five softkeys underneath the display provide specific operations depending on the unit’s configuration. The other push buttons (from
left to right) are used for volume control, monitor illumination, summary report, and code markers. The CHARGER ON indicator displays the status of the
unit’s power supply.
This input module on the front panel and the Main System Board provides a beeper for the AC/DC Power/Battery Charger.
The Controls PWBA is physically located in the front panel assembly. Units that are equipped for voice recording include a microphone and audio signal

E Series Options
The following sections describe the E Series options.
12 Lead Option
The ZOLL E Series 12 lead option is used to ac qu ire ECG d ata needed to assist in the diagnosis of myocardial infarction (“heart attack”), often caused by
a coronary artery occlusion. The 12 lead ECG can be viewed on the display one lead at a time in monitoring and diagnostic bandwidths and printed in the
standard 4x3 format with 12 simultaneously acquired leads.
The 12 lead option provides for the recording, printing and automated analysis of 12 lead ECG using GE Marquette 12SL™ Analysis and supports the
transmission of these reports by fax to a remote locat ion, such as a hospital. In t he pre-hospital en vironment, the 12 lead rep orts can be faxed to a physician
as the patient is en route to the Emer gency De partment . As a result, t he physici an can ini tiate hospita l accommodati ons immediately, such as ac tivating the
staff of the cardiac catheteriz ation lab, prior to the pa tient’s arrival and subsequent treatment. Or the patient may be treate d in the pre-hospital environment
with thrombolytic agents.
The 12 lead cable is required to produce 12 lead reports. E Series unit must have the 12 lea d option installed. All limb leads and V-leads must be connected
to initiate a 12 lead acquisition. Printed 12 Lead bandwidth is use r configurable to be ei ther 0.05-150 Hz (per AAMI EC1 1) or 0.05-40 Hz. The 0.05 -40 Hz
bandwidth selection is used to reduce noise art ifact in t he h ig h end of the diagnostic frequency range. Reports can be printed in a standard 4x3 or Cabrera
format. Faxed reports can be configured in a 2x6 format in addition to 4x3 and Cabrera formats.
The GE Marquette 12SL Analysis algorithm provides measurements of the 12 lead waveforms along with interpretive statements. The algorithm is
interpretive, not “diagnostic.” (A physician should always confirm interpretive statements. A diagnosis requires a complete clinical assessment including
other modalities, such as a physical examination.) 12SL produces global waveform measurements as well as a measurement matrix containing
measurements on each lead. Both the interpretive statements and measurement matrix are configurable to be printed or not printed.
The acquired 12 lead with 12SL may be faxed to a remote location using landline or cellular phone technology. Specific PCMCIA fax modems are
supported and the modem determines the specific phone compatibility. The E Series supports Group 3 facsimile, Class 1, Class 2 and Class 2.0. 12 lead
reports may be re-printed or re-transmitted using the Patient Records capability. Individual patient records may be selected based on patient ID, date, and
time.
Pulse Oximetry (SPO2)
The ZOLL E Series pulse oximetry option enables the user to continuously, noninvasively, and painlessly monitor the percentage of oxygen saturation of
arterial hemoglobin at a peripheral measurement site (i.e. foot, toe or finger.)
The oximetry sensor contains two light emitting diodes, or LEDs, that transmit red and infrared light through the body’s extremities. A photodetector
receives the transmitted light. Oxyg en saturat ed bloo d absorbs light d if ferently than u nsaturated b lood. Th us the a mount of red and infrared light absorbed

by the blood flowing through a suitable peripheral area of the body, such as the finger in adults and the foot in neonates, can be used to calculate the ratio
of oxygenated hemoglobin to total hemoglobin in the arterial blood. The monitor displays this ratio as percent SpO

95% to 100% at sea level.
The E Series uses a Masimo® Pulse Oximetry Circuit Board which features a fundamentally distinct method of acquiring, processi ng and reporting arteria l
oxygen saturation and pulse rate. The E Series’ SpO
module (Masimo® Circuit Board) connects to the Masimo sensors and reports monitoring results

(oxygen saturation, pulse rate, pulse waveform, etc.) via a serial digital interface to the E Series system board. The E Series system provides isolated DC
power and serial communication to the SpO
Board via the Isolated Power Supply board.

End Tidal Carbon Dioxide (EtCO2)
The ZOLL E Series EtCO2 option continually and noninvasively monitors the patient’s carbon dioxide in respiratory gases and from these measurements
computes End Tidal CO
In addition, the unit can configure an alarm to sound when the unit detects EtCO
set by the user. This option is intended for use in all critical monitoring environments including ventilato r sup p ort, patient transport, and anesthesia and is
intended for monitoring all patient types, including adu lt, pediatric, and neonatal.
E Series units equipped with software revision 2.00.000 or higher support two End Tidal Carbon Dioxide (EtCO2) monitoring options for the continuous
measurement of respiratory carbon dioxide (CO

The first option uses a unique, mainstream, solid-state, infrared sensor called the CAPNOSTAT® 5 Mainstream CO2 Sensor. The CAPNOSTAT 5 CO2
sensor is attached to an airway adapter that connects to an endotracheal (ET) tube or other airway and measures gases flowing through these breathing
circuit components. A disposable mouthpiece may be connecte d to the adapt er for moni toring non-intu bated pat ients. A CAPNO
for use with non-intubated patients. This option provides for O
delivery while monitoring expired CO2.

The second option is a sidestream sampling system called the LoFlo™ CO2 Module. The LoFlo module contains a gas sampling pump, which draws sma ll
samples of gas from the patient’s airway via a nasal/oral cannula or airway adapter, and passes these gases through a solid state infrared sensor (located
away from the patient’ s airway) that mea sures CO
. While the sidestream system is typica lly used on non-in tubated patients, it can also be used fo r EtCO2
2
measurement on intubated infant, pediatric and adult patients. The sidestream system should not be used, however, on patients who cannot tolerate the
50ml/min removal of the sample gases from their breathing circuit. The sidestream module uses specially designed cannulas and airway adapters for
sampling airway gases and passing them through an integrated sample cell, which connects to the LoFlo module ’s CO
sensor. These cannulas inc orporate
2
a filter and sample cell, providing maximum filtration of fluids and contaminants, and protecting the system from aspiration of these fluids.
In both systems, the CO2 sensor generates infrared light and beams it thro ugh the airway adapt er or sample cell to a detec tor on the opposite sid e. CO2 from
the patient, flowing through the mainstream airway adapter or sample cell, absorbs some of this infrared energy. The E
Series unit determines CO2
concentration in the breathing gases by measuring the amount of light absorbed by gases flowing through the airway or sample cell.

The E Series unit displays EtCO2 (the concentration of carbon dioxide detected at the end of each exhalation) as a numerical value in millimeters of
mercury (mmHg), percent (%), or kilopascals (kPa). In addition, the unit can display a capnogram. This capnogram is a valuable clinical tool that can be
used to assess patient airway integrity and proper endotracheal (ET) tube placement. The unit calculates respiration rate by measuring the time interval
between detected peaks of the CO2 waveform. The technology differentiates between waveforms caused by breathing and those caused by ca rd io gen i c
oscillations and artifact.
Noninvasive Blood Pressure
The Non-Invasive Blood Pressure (NIBP) option on the E Series unit allows you to take a single blood pressure measurement, STAT measurements
(automatically repeated measurements over a 5 minute period), or automatic measurements at repeating pre-selected intervals.
The ZOLL E Series NIBP option is indicated for the non-invasive measurement of arterial blood pressure for resting patients in critical care and transport.
The NIBP option is designed to measure blood pressure for adult and pediatric patients.
The patient blood pressure cuff and hose connect to the E Series unit through the NIBP connector on the rear panel of the unit. The NIBP button on the
front panel of the E
softkeys on the NIBP menu.
The NIBP module measures the oscillometric pulses transmitted throu gh the blood pressure cuf f and hose, and ca lculates the bloo d pressure measurements
accordingly. The blood pressure information (including the patient’s systolic, diastolic and mean blood pressure values) is shown on the E
Series allows you to initiate and terminate blood pressure measurements. You can also initiate and terminate measurements using the
Series monitor.
